srEcIFmATIoN forming part of Letters Patent No. 631,755, dated August22, 1899. Application filed June 17,1899. Serial No. 720,925. (Nomodel.)

To ctllfwhom/ it 11mg/ concern.;

Be it knownthat I, WILLIAM II. SHICK, a citizen of the United States ofAmerica, and a resident of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inHeaters, of which the following is a specification.

My invention relates more particularly to water or steam heaters of thevertical sec- Io tional type; and it consists in a novel constructionand arrangement of parts whereby to provide for a supply of air abovethe fire for the purpose of securing more complete combustion of thefuel-'gases and the increase r 5 in economy and eectiveness which it iswell known result from such improved combustion.

The invention is fully described in connection with the accompanyingdrawings, which zo illustrate the application of xnyimprovemen ts to avertical sectional heater.

Figure 1 is a half front elevation, and Fig. 2 is a half sectionalelevation on the line .fr of Fig. 3, the upper portion of the heaterbeing cut away as having no connection with my present improvements.Fig. 8 is a crosssectional view on the line y y of Fig. 2.

A represents the front body-section, C the rear body-section, and B Bintermediate ver- 3o tical body-sections, all of which rest uponbase-plates D D2, which form the ash-pit D. The fire-box is formedbetween the inner walls of the sections A and C and the legs of theintermediate sections B B', above the grate E.

A is the usual fire-door, and d' d2 the ashpit and draft doors. Theupper heater, tlues, and smoke-pipe outlet are not shown.

C indicates the Water connection to the rear section, which is in turnconnected with the 4o adjoining sections, so as to maintain all incommunication, as usual.

In the section C, I provide vertical air-passages c, one'on each side ofthe fire-door A', these being formed, as shown, by pockets or recessesfrom the inner face of the section, open at the bottom, so as tocommunicate at dwith the ash-pit, and by vertical plates or' covers Fremovably secured to the section C. These plates `are each provided, asshown,

5o with a screw-threaded opening near the top, arranged at right anglesto the air-passage c,

into which is screwed a pipe G, having` a series of perfor-ations gopening toward the other parallel pipe. The other ends g2 of these pipesare not perforated and each is provided With a collar g.

In erecting the furnace the intermediate sections B B are successivelyplaced in position against the rear wall-section C and each other, Withsuitable water-tight joints con- 6o necting them, and finally the frontwall-section is similarly connected, the latter being provided withthimbles a, having the openings large enough to looselyT receive andinclose the ends g2 of the pipes G, which enter 65 the thimble-openingsuntil the collars g are about in cont-act with the inner face of thesection, and thus serve to practically close the opening around theinserted pipe ends.

A slide or gate h is provided on the outer face 7o of the section A toopen or close the pipe G to the outer air, which latter may also beadmitted, if desired, to the other end of the pipe G'through ahorizontal opening c' into the Vertical air-passage c, said openingbeing provided with a similar slide or gate. It is evident also thatthese vertical air-passages c may be provided in the front wall-sectionA as well as in the rear Wall-section C, as shown.

When either the draft-door or ash-pit door 8o is open, air Will beadmitted through vertical passage-ways c to the perforated pipe G, andthence to the combustion-space above the tire, thus furnishing theincreased supply of oxygen necessary for complete combustion.

When the slides h are opened, outside air Will be admitted directly tothe pipe G, and thence to the combustion-space, this being the onlysupply that is provided, as may be desired, when the ash-pit is closedand forming an ad- 9o ditional supply, if required, When the latter isopen.

1. In a heater the combination with a Wallsection provided with anair-passage communicating with the ash-pit and rising vertically in thefire-box wall thereof, of a separatelyformed perforated pipe or conduitconnected with said vertical air-passage, extending horizontally throughthe combustion-chamber and Ioo communicating at its other end with agated opening through the parallel wall-section.
